'TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWARD Jr'LnYBUnN, of Lexington, inthe county of Rochbridge, and State of Virginia, 4have invented anl improved Automatic Rake for Harvesters; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had te the accompanying drawings, making. part of this specification, in whichf- Figure 1, sheet 1, is a perspective View of the improved rake and reel, showing the rake-arm in a posi-tion 1 to serve as a reel or gatherer. v v

Figure 2, sheet 1, is a perspective view of the same parts, showing 'the raliearm in a position for discharging a gevel. V p

Figure 3, sheet 2, is an enlarged top view of the devices for supporting and giving the desired movements to the rake-arm. y 4

Figures 4,'5, 6, and 7 represent said devices in their several dierent positions. Similar letters of reference indicate corresponding parts in the several figures. i This invention relates to certainnovel improvements in operating that class of rake-arms which sweep over the platform in the path of a horizontal plane, so as to deliver the cut grain in gavels at onerside of the machine,

and then rise and assume such a position as to serve as reel vor gathering-arms for gathering in the standing' grain to the cutting-apparatus. l 1 f i i p The main object of my invention is to simplify such a raking and reeling-device, by dispensing with spurred wheels, and employing instead thereof revolving jointed rods and stationary cams, so -constructed and' arranged as to give positive movements. to the rake and reel-arm, and hold itiirmly in the different positions which it is To enable others skilled in the art to understand my invention, I will describe-its construction and operation. In the accompanying drawings, A represents a platform of a segment forni, which may be applied to the front or rear side of. a single or double-wheel draught-frame, and connected to such frame by means of joints, so that it will rise and fall, and conform` to the undulations ot' the ground. B'represents thereel-shaft, 1which is supported above the front end of' the platform, and parallel thereto, by means of an 'outer frame, C, and an inner post, D, both of which are sustained upon the platform, so as to move in harmony with it.4 ,i This :rel-H shaft may have on its inner end a pulley, a, or its equivalent, by which rotary-motion can be imparted to it from driving-devices upon Athe main frame. If desirable, the reel-shaft may be driven bymeans of' aueltensible shaft, an'extensihle belt, or by any other means which will allow it, together with the platform, to rise and fall, or vibrate freely without binding or strain. It' desirable, the pulley a may be applied upon its shaft B "by means of a clutch, or pawl and ratchet, so that, when the driving-devices are turned backward, the shaft B will not be turned backward. v Y

Upon the shaft B three parallel reclbars, 6 b I1', are suitably secured for gathering in thestanding grain to be cut. These bars are appliedl upon three sides of the shaft, so as to leave a space on that side of the shaft which is opposite the reel-bar 11', as shown in iig. 2,`for the rake-arm E, when this arm is in position for-reeling', as shown in g. 1. This rake-arm when in position for reeling, is in a plane parallel to the reel-shaft, and occupies the same relative position therewith that'ithe reel-bars bpb b do, so as to serve, for all'intentsand pi1rposes, as a reel-arm for pressing the standing grain toward the cutting-apparatlis. The reel-bars 6 b b' are each secured to their shaft by two radial arms, as shown in figs. 1 and 2; but the rake and reel-erin E is carried by n single oblique arm, E', which extends inward to a point which is near the inner end of the reel-shaftB, and is attaehedto a collane, which is applied loosely upon a reduced cylindrical portion, c', of said shaft, as shown in figs. 1, 5, and 6. 'This rake-arm E is secured to an angular arm, cZ, a portion, d', of which forms the pivot of the rake, and passes through two ears, e c, on collar c, so as to stand at right angles to the axis of the reelshaft, as shown in iig. 5. A bent arm, f, is secured to the end of the pivot d', which arm has a Weight,g, secured or formed on its outer end, the object of whichis to bring thorake-arm quickly in position, to serve as a reel, after it ceases to serve as a rake, and rises from the platform. The inner portion of said arm f is bent, so as to assume a position at right angles, or nearly so, to the reel-shaft when the rake is in position to operate as a reel, and thus revolve in the path of a vertical plane. At the angle which is formed by. bending this arm 'maso 2..

f a.' short rod, 7i, is linked or pivoted at one end, the opposite end of which is attached,`by a universaljoint, h", 7

to the inner arm of the reel-bar as .clearly shown in igs. 1 and 4.

Near the -point oi' connection of the rod h with the arm f, and on that side of this arm which is upper- `most when the rake is sweeping the grain from the platform, I apply an anti-friction roller, c', as Vshown in figs,

1, 4, 5, and 6. i

0n the outer side of the reel-post D, and at the upper end thereof, a circular cam-plate, G, is' secured, a portion, G1, of which is bent inward, so as to receive the arm after the' rake has delivered a gavel, and move Vthe rake into reeling position. The other portion of the face of this cam-plateG is dat, and stands in a plane perpendicular to the platform, so as to serve'as an abutment for keeping arm f in proper-position.

When the rake-arm descends to 4a position for commencing to sweep around over the platform in a plane parallel thereto, the pivot el of the rake will stand perpendicular to the platform, and the anti-friction roller 'L' will abut against thelow'er side of an overhangingplate, G2. The `armfwill also have been brought above th level of the straight edgei of the cam-plate G, as shown in fig. 1. This arrests the revoli'ing motion of the f rake and ts pivot, and holds theloose collar c stationary `for a time. As the reel-shaft continues to move, the

connecting-rod l1. will cause the rake-arm Yto `move Aaround in the path of a horizontal plane sutciently far to discharge the Acut grain from the inner edge of thel platform, as shown in iig.'2. When this has been effected,

the roller willhavezpassed frombene'ath the arresting-plate G2, and the armf brought in contact with the camsuriface-G. As4 the reelfshaft continues to turn, the rake-arm will rise with it, and be cased into reeling position again, before it iscarried over upon the standing grain.

. The weight g on the outer end of the arm f is designed for bringing the rake-arm quickly `into reeling position after' the"`discharge oi' la gravel, so that there will be little or no' sliding friction caused by the action of cain`p1:.|.t A G Glnpon the arm f. This weight also serves, by its contact lwith the inne;` arm of the reel-bart', as a m'e of sustaining the ralre-arm against pressure while serving as a reel or gatherer.

It will be seen, from the above description, ,thatl the rake-arm moves around with'the rcel-arms in the path of a vertical plane, and'thus serves as one of the reel-arms for gathering in the standing grain'to be lont; and, whenthis arm has been brought overthe'cutting-apparatns or front endoif the platform, its revolution with the reel-shaft is arrested, and it is caused 4to siveep around'in thev path cfa horizontal plane suilicicntly far to discharge the grain from the platform.

Having described my invention, what I claim, and desire tosecureby Letters ]'atent,A is- -1. Connecting the rake-arm E to a loose collar,"c', on reel-shaft 13, by Ameans of a pivot, d', carrying. an arm, f, in combination lWith the jointed connecting-rod substantially as described.
